Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0053] The difficulty of processing the logarithmic curve spiral groove of the convex hemisphere lies in the control of the depth of the groove. During ion etching, the ion beam is projected from one direction to the surface of the convex hemisphere in a straight line, and the convex hemisphere is driven by the tooling to rotate around its axis at a certain speed. In this way, the plurality of spiral grooves evenly distributed on the entire spherical surface of the convex hemisphere can be etched. Based on this, the present invention provides a mask for processing the convex hemisphere of the gyro motor, which is used for proce...

Abstract

The invention provides a mask for machining a convex hemisphere of a gyro motor and a machining method of the mask, and solves the problem that the performance of the gyro motor is influenced due to the fact that the machining precision of the convex hemisphere cannot be guaranteed by an existing machining tool of the convex hemisphere. The mask for processing the convex hemisphere of the gyro motor comprises a mounting sleeve, a hemisphere shell and an extension sleeve, the mounting sleeve, the hemispherical shell and the extension sleeve are sequentially and coaxially arranged, and a plurality of logarithmic curve spiral holes matched with the logarithmic curve spiral grooves of the convex hemisphere in shape are formed in the hemispherical shell in the circumferential direction; the invention provides a processing method of a mask for processing a convex hemisphere of a gyro motor. The processing method comprises the following steps: step 1, primary processing; secondly, a positioning mandrel and a positioning clamp are machined; step 3, processing an outer spherical surface; fourthly, the logarithmic curve spiral hole is machined through numerical control milling; fifthly, burrs on the outer spherical surface are removed; step 6, separating the mask workpiece from the positioning mandrel; and seventhly, burrs on the inner spherical surface are removed.

Description

technical field [0001] The invention belongs to the field of gyro motors, and in particular relates to a mask for processing convex hemispheres of gyro motors and a processing method thereof, in particular to a mask for ion etching of spiral grooves of convex hemispheres of gyro motors for dynamic pressure air bearings and the mask and its processing method. processing methods. Background technique [0002] The three-float gyroscope is the small gyroscope with the highest precision and the longest lifespan among electromechanical gyroscopes at home and abroad. It is mainly used in satellites, manned and cargo spacecraft, space stations and other inertial navigation fields. The dynamic pressure gyro motor is the "heart" of the three-float gyroscope. ", which plays a vital role in the performance and life of the three-floating gyroscope. [0003] The dynamic pressure air bearing is the key component in the dynamic pressure gyro motor, and the dynamic pressure effect and air f...
